So me and a friend finished doing a swap on my civic. Now when the car starts up w/ out the exhaust being attached yet, strait off the header and down pipe, she idles wicked rough. From 1.5k- 2k till she warms up, then she settles down around her normal 1k idel and then this very anyoing teakettle high pitched noise comes in. Its there no matter what RMP your at after the car is warmed up... we think that noice is a belt going bad... any ideas on any of this
